Due to the close proximity of antennas in a Rover, it is quite likely that operation in the narrowband segment will "self-QRM" the CU2QSO transceiver, causing it to believe that the channel is in use; thereby holding off a transmission until after the narrowband transmission is completed.  Alternately, PTT circuits may be employed to assure that -- when another 2 meter transceiver is PTT'd -- the CU2QSO TNC is powered-off.  This will absolutely guarantee full compliance.  It is suggested that each Rover test their system against the first method before adding the complexity of the second method"

Hmm - maybe in a rover...  but as I understand it, this technology is now allowed
for home stations where this method of preventing more than one signal at a time
would not be sufficient.  

It would seem that this hasn't been really throught out for the home station.
